[Spice-devel] Inverted video on RHEL 64-bit connected from Win7 Client...

[Naga Mohan Pothula]

Hi, 

I verified Video driver info in RHEL6 Guest connected from Ubuntu 10.04 LTS 
client and Windows 7 client.
I did the same for Fedora12 Guest.

Qxl driver is kicked in RHEL6 Guest  but not in Fedora12 Guest. 
But here, we need to see why it works when RHEL6 Guest connected from Ubuntu 
client but not with Windows 7 client.
Please refer the attached files for your reference.

The loaded modules related to video driver is same in RHEL6 connected both from 
Ubuntu and Win7 Clients.
Please let me know if anyone knows approaches for fixing this problem asap.


Thanks,
Naga.

Thank you all for your prompt responses.

This issue comes all the time for Youtube videos. 
Consistent flickering happens for Disney videos because frequent flipped and 
normal videos appear.

I'm using Ubuntu 10.04 LTS to host KVM Hypervisor/Spice server.

My concern here is this issue happens with RHEL6 only not with Fedora12 
connected  from Windows client.
If this issue happens even with Fedora12 then I can think of spice module 
location before creating JPEG.
Generally, when we capture screen or any particular region, the bitmap 
co-ordinates are reversed. So we need to specify negative for the co-ordinates 
before converting to JPEG image.
Hence, i need to see in other directions for fixing this bug.


Regards,
Mohan.

Hi Mohan
I have exactly the same Inverted video issue.  Both spicec/spicy client are OK.
Only happen when I use Windows spice client.

My setup:
Rhel6 KVM host hypervisor spice server.
spice-server.x86_64           0.4.2-15.el6
pixman-spice.i686             0.13.3-5.el6
celt051.x86_64                0.5.1.3-0.el6
qemu-kvm.x86_64               2:0.12.1.2-2.113.el6_0.8
I mean to upgrade spice server  but too busy to do that.

Spice guests tested are Ubuntu 10.10 and 10.04 LTS

I am glad that you tested all the latest and still having the same issue.
That experiment will save us lot of time. Tx.

What OS Distro you use to host KVM Hypervisor/Spice server ?

Cheers
The Ha
